Patented Oct. 11, 1938 PATENT OFFICE LAMP SHADE CarlY W. Huilage,Chicago, Ill., assignor to Reynolds Metals Company, Richmond, Va., acorporation of Delaware Application May 7, 1938, Serial No. 206,580 YClaims.

The present invention relates generally to new and improved lamp shadesand to an improved material for making the same, and an object thereofis the provision of a lamp shade formed with exterior opaque,mirror-like reiiective panels of metal foil arranged angularly incorrugated form and provided with translucent spots in regulargeometrical formations so that when the shade is placed over a lightedelectric bulb a diffused light emanates from the translucent spots whichare reflected in the mirror-like panels to contribute a unique andattractive ornamental effect.

It is a'further object of the invention to form a lamp shade of opaquemetal foil, preferably aluminum foil, of a highly reflective nature, and

provided with perforations, openings, or circular holes, arranged indesigns, and to laminate such foil upon its inner side With a solidsheet of translucent material, such as a thin sheet of ordinary paper,and to so arrange the laminated paper and foil stock as to obtainmirror-like reflective foil panels in the lamp shade, which whenilluminated Will by reflection reproduce in whole or in part the lightrays passing through the translucent sheet and through the openings incertain of the reflective panels.

It is a further object of this invention to arrange a flat, generallyrectangularly shaped blank of perforated metalfoil, backed with atranslucent paper, into a generally frusto-conical or cylindrical shapeadapted to fit conventional lamp shade frames, corrugating the foil andpaper stock in a series of V-shaped ridges and V-shaped grooves, havingsharp longitudinal crease lines; and to arrange the perforations in thesaid foil in longitudinal lines in the crease lines of the said V-shapedridges and V-shaped grooves.

It is a further object of the invention to provide color eifects in suchlamp shades by utilizing a translucent colored paper of any desired tintas a backer for the perforated foil, or to attain generally similarresults by placing colored Cellophane, or similar colored iilms, as acovering or a lining for the lamp shade.

These and various other objects and advantages will be readilyunderstood when taken in connection with the accompanying drawing of apreferred embodiment of the invention, in which modifications can bemade without departing from the scope of the appended claims.

In the drawing, Fig. 1 is a perspective view of a lamp shade,illustrating a preferred embodiment of my invention.

Fig. 2 is a plan view of the lamp shade shown in Fig. l with a portionbroken away.

Fig. 3 is a semi-diagrammatic side elevation of v the lamp shadeillustrated in Fig. with a portion of the same showing the reflectiveeffects 5 obtained when the shade is illuminated.

Fig. 4 is a fragmentary cross-section taken upon the line 4 4 of Fig. 2but with an additional showing of a colored Cellophane outer coverlng. y0` Fig. 5 is a fragmentary view of the laminated 1 perforated foil andtranslucent backing material which constitutes the stock for making thelamp shades embodying my invention.r

Fig. G is an enlarged fragmentary View of one of the translucentopenings lying in one of the grooves of the corrugated lamp shade andillustrates certain reflective yeffects secured by my invention.

In these gures a conventional lamp shade frame I0 illustrated ingenerally frusto-conical form has positioned thereon a lamp shade i2,and is provided as indicated with an electric bulb I3. The lamp shade isformed with an outerv layer of opaque, highly reiiective metal foil,preferably aluminum foil, It, and an inner layer of translucent paper orsimilar material I which may be tinted as desired.' The combined metaland foil stock is deformed into a series of longitudinally runningV-shaped ridges I8 and V- shaped grooves 20, giving a corrugated effect,sharp crease lines 22 being at the apeX of each ridge I8 and sharpcrease lines 24 being formed in the bottom of each groove 20. Suchformation provides substantially rectangular panels 26 35 of a highlyreflective or mirror-like character running longitudinally of the shadeI2 which Will ordinarily be of equal size, and the adjacent panels 26 inany one groove 20 will ordinarily be arranged so as to be at an angle ofsubstan- 40 vtially ninety degrees, or preferably less, one to theother.

The outer layer of foil I4 in the embodiment of my inventionillustrated, is provided with a series of perforations 28 arranged inlongitudinal lines at the ridge crease lines 22 and at the groove creaselines 24; the translucent paper stock is visible through perforations28, and being of different color .than the foil layer I4, clearly showsas a series of paper spots 30. The perforations 50 28 will normally beformed in a regular pattern, spaced equidistant one from the other, orin some design, as illustrated. Where the shade is generally cylindricalin form, each panel 26 Will lie in substantially a single plane, andthis is sub- 55 stantially true of the panels 26 as illustrated althoughthe frusto-conical shape of the lamp shade l2 causes the individualpanels 22 to vary slightly from lying in a single plane due to the factthat the angle of V-shaped groove 20 tends to `be slightly smaller atthe top of the shade than at the bottom; however, for all practicalpurposes, the individual panels 26 are and will be designated as eachlying in a single plane, and this application is intended to includesuch panels in generally cylindrical lamp shades, as shown.

When lamp shade l2 is illuminated translucent paper spots 30 will glowwith light and certain light rays will emanate therefrom. Certain of theilluminated spots and light rays will be reflected in panels 26depending upon the position of the observer. Referring to Fig. 3, if theobserver is directly in front of the lamp shade, spots 30 located ingrooves 20 in' the Zone indicated as A, will be reflected in the panels26 of such zone; in zone indicated as B the translucent spots 36 in boththe ridges I8 and in the grooves 20 Will be reflected; in the Zone Cthere will be reflections of the illuminated spots 3Q of the ridges I8only.

Reflection of light through and the illumination of the paper spots 30,together with reections thereof in the highly reflective or mirror-likepanels 26, give a soft and diffused light from the shade. The brightnessof the metallic foil and the soft glowing of the translucent spots 3l?together give an attractive and unique appearance, which may be modifiedby placing an outer covering, indicated as 32, of colored Cellophaneupon shade l2.

It is to be understood that while the illustrated form of the inventionwhich I have described, represents a preferred embodiment, I do not wishto limit myself to the details as shown, since it is obvious that thesame may be widely Varied without departing from the essence of theinvention which comprises the mounting of tra-nslucent material upon anouter layer of highly reflective metal foil having openings therein andarranging a lamp shade with a series of reilective panels adapted .toreflect light showing through the translucent material spots in the saidopenings, and therefore the appended claims are intended to define thescope of my invention.

Having described my invention, what I claim as new and desire to secureby Letters Patent is:

l. A lamp shade comprising an outer layer of highly reflective metalfoil and an inner layer of translucent material mounted thereto, whichincludes openings in said outer layer and reflective panels formed insaid outer layer angularly disposed one to another and positioned toreflect light emanating from said openings.

2. A lamp shade comprising an outer layer of highly reflective metalfoil having a plurality of openings and an inner layer of translucentmaterial mounted thereto and co-extensive therewith so as to cover saidopenings, which includes a series of reflective panels formed in thesaid shade disposed at an angle of ninety degrees, or less, one toanother, so that light emanating from said openings is reflected in saidpanels.

3. A lamp shade comprising an outer layer of highly reective metal foiland an inner layer of translucent material mounted thereto, whichincludes a series of adjacent light reflective panels each lyingsubstantially in a single plane and each angularly disposed to the paneldirectly adjacent, said panels being arranged to form alternatelyV-shaped grooves and ridges, .and openings through said outer foil layerbut not through said translucent layer, the said openings being formedin regular designs approximately in the bottoms of the grooves and atthe tops of the ridges.

4. In a lamp shade, an outer layer of highly reflective metal foil, aninner layer of translucent material mounted to the said foil, a seriesof corrugations in said layers alternately forming tl-shaped ridges andgrooves, and openings formed in said outer layer of reflective foilonly, whereby light passing through the translucent material and throughsaid openings is reflected in said outer reflective foil.

5. In a generally cylindrical lamp shade, an outer layer of highlyreflective foil, an inner layer of translucent material mounted thereto,a series of equal and alternate V-shaped grooves and ridges corrugatedin the said layers, forming a series of light rellective panels upon theexterior of said shade, openings in the foil layer but not in thetranslucent layer disposed approximately in the bottoms of the groovesand at the tops of the ridges thereby forming spots of translucentmaterial through which light rays may pass, capable of being rellectedin said reflective panels. v
